If you get intermittent i2c bus problems I would guess it is
an electrical problem. Or does it work on one boot (then reliably)
and not at all on some other boot?
The bttv-i2c module has a debug parameter and a i2c_hw switch
to drive the bus by hardware or software (bit banging). You could
try to play with this. You could also try to play with the
timings in bttv_i2c_algo_bit_template.
